must I use var

HI, I was reading the docs and I see this: > /* This is how it should be done. */ > class Cart > { > var $todays_date; > var $name; > var $owner; > var $items; > > function Cart() > { > $this->todays_date = date("Y-m-d"); > $this->name = $GLOBALS['firstname']; > /* etc. . . */ > } I don't see the point in doing var $todays_date; and $this->todays_date = date("Y-m-d"); The latter works without the need for the "var". Why should i use "var"? Thanks, Peter http://www.readbrazil.com/ Answering Your Questions About Brazil
